Super Tank Battle R - Type X is an Android game developed by UnknownProjectX. This game has been around for over four years and has recently undergone some improvements. The game has removed some not user-friendly design and old features, reduced its size, and enhanced its graphics. The game's playing map is randomized, which adds an element of surprise to the game.

The classic game rule remains the same: defend your base and destroy all enemy tanks. If your tank or base is destroyed, it will be game over. Each map has 20 enemy tanks to defeat. The game features 500 maps that are fully unlocked, providing hours of gameplay.

Overall, Super Tank Battle R - Type X is a classic game that has been improved with better graphics and a randomized playing map. It is a game that is easy to pick up and play, making it a great addition to your mobile phone. However, it would be great to know more about the developer and their background.
